Breast Cancer

Among all cancers in females, he takes consumers. In most cases, breast cancer develops in the presence of precancerous changes. This is primarily a benign mammary dysplasia and papilloma ducts.

Breast cancer is represented macroscopically nodular and diffuse forms, along with cancer with the nipple and the nipple with the field (Paget's disease in the breast). For the nodular cancers are seen as an the node creating a diameter all the way to several centimeters. In some cases, a decent knot, is permeated with whitish layers tissue penetrating into the surrounding dimply skin, on other occasions - a soft, juicy about the cut, splits easily. Diffuse cancer of prostate is covered for any considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades the skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads across the surface from the breast and many types of the iron is included which has a dense shell.

In histological structure are the following kinds of breast cancers:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive cancer of the breast could be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is characterized by varying degrees of tissue and cell irregularities, which allowed to distinguish different level of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which often has the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The causes of cancer of the breast often are hormonal changes within the body: the entry into menopause, if you find a dynamic restructuring with the hormonal regulation of the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, one's body will go through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most tuned in to these changes, the breast tissue begins to dissolve and stay replaced by fat.

Scientifically established that this female hormones estrogen-, plays an integral role in the development of breast cancer. The excess hormones inside body produces a favorable background for developing the sickness. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (more than twelve months) to relieve the chance of developing cancer of the breast. On the other hand, abortion lead to hormonal "explosion" inside a woman's body that can trigger the development of tumors. So far there is no consensus in regards to the impact on the development of tumors of hormonal contraceptive drugs, yet it's thought that these drugs reduce potential risk of developing breast cancers, but increase the risk of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast might cause harmful environmental factors: the environment, and also inflammatory diseases previously deferred breast - mastitis.

In addition, patients with a category of first-degree relatives with breast cancers (mothers and sisters) chance of developing a tumor increasing by over half - familial forms of cancer.

Benign breast diseases such as fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone tend not to lead to cancer, but as well, create an unfavorable background due to the development.

The reason for breast cancer would be the effects of radiation, such as irradiation of the chest for other diseases (lung tumors, the lymphatic system), prolonged and frequent chest X-ray studies on inflammatory diseases or pulmonary tuberculosis.

Constitutional obesity can result in cancer with the breast and female the reproductive system, having an excess fat within the body, it is a different endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are some forms in the growth of breast cancers:

- Nodular form, the most common, is seen as a dense knot of 0.5 to cm or higher, it can be seen as a all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without clear boundaries, "spreading" with the breast and skin. For the first two forms are characteristic warning signs of inflammation: pain in the breast, a bright red colorization of the skin it raises body's temperature to 39 degrees C. In view of such symptoms often occur, and errors in diagnosis of patients treated for inflammatory diseases, that happen to be named and so are referred to these forms breast cancer. When tubular carcinoma breast cancer cover like a "skin" of the contracting and decreasing in proportions.

In certain cases, breast cancers manifests inside form of metastases in the lymph nodes around the affected side, often doesn't detect the tumor itself - show hidden breast cancer.

For small tumors with the breast, any symptoms arise. The most observant women and their husbands have the ability to detect tumor site inside gland by accident, but in the large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks in favor of a benign tumor. Signs of malignancy other: a decent knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, might be firmly fixed for the surrounding tissue or skin, usually painless, can reach a tremendous size (more than three to five cm and sometimes 10-15 cm).

Need to evaluate the surface from the skin within the tumor: the malignant process will likely be observed retraction with the skin, collecting inside the folds, wrinkles, a symptom of "lemon peel" - an area swelling with the skin on the tumor, is often a direct tumor invasion to skin surface, then it is a bright red color and sprawl as "cauliflower."
